Logging intervals
Description
Specify time intervals during which to log data
Category: Data Import/Export
Settings
Default:[-inf,inf]
Specify a two-column matrix that contains real,
double
values that indicate the start and stop time for an interval in which you want to log data. The matrix can contain any number of rows to specify any number of logging intervals.The matrix elements cannot be
NaN
.Intervals must be disjoint and ordered. For example, you can specify these three intervals:
[1,5;6,10;11,15]
.
Tips
The logging intervals apply to:
Time
States
Output
Signal logging
To Workspace blocks
To File blocks
Data logged to the workspace using a Record block
The logging intervals do not apply to:
Final states data
Data logged using scopes
Data logged to a file using a Record block
Data in the Simulation Data Inspector
Logging intervals do not affect data displayed in the Record block or using dashboard blocks.
Logging intervals are only supported when you select Single simulation output. The single simulation output is a
Simulink.SimulationOutput
object that contains all logged data that logs to the workspace.When you specify an interval that includes a time before the simulation start time or after the simulation stop time, no data is logged for that interval.
The Decimation and Limit data points to last parameters also apply to logged data when you specify logging intervals.
When you change the logging intervals while using the Simulation Stepper to step through a simulation, the new logging intervals do not apply until you step forward.
SIL simulation mode supports logging intervals for data that logs to a
Simulink.SimulationOutput
object. In SIL mode, specified logging intervals are ignored without warning for:Data logged using a To File block
MAT file logging (enabled with the MAT-file logging configuration parameter)
PIL simulation mode does not support logging intervals. Specified logging intervals are ignored without a warning message.
Dependencies
To enable the Logging intervals parameter, select Single simulation output.
